Automated Guided Vehicles From The Global Production Optimiser…
FFT is a supplier of complex production systems and a manufacturer of its own system components for joining, folding and separating, for image-supported processes, and for handling and transport tasks. As a system provider, however, FFT is not limited to its own products. For example, FFT purchases robots and many other components from other manufacturers.
Franke is the inventor and manufacturer of wire race bearings. Wire race bearings can be integrated directly into the enclosing structure. Franke bearing assemblies can be customized to the customer’s requirements. They are available in any size, with individual bores and toothing and in numerous materials such as aluminium, stainless steel, carbon or as a 3D-printed housing.
AGV as a separate product category…
In order to link several system components together logistically, FFT requires, among other things, automated guided vehicles (AGVs). These can be fully automated on one hand, and can be used very flexibly on the other. Even if production processes and transport routes change, the self-propelled vehicles can be adapted to the new situation with relatively little effort.
Such self-propelled vehicles were required for FFT’s plant projects in China and Vietnam in 2021. “As FFT, we jointly decided to develop and manufacture these ourselves in order to subsequently turn them into a separate product category,” reports Account Manager Christian Schuster, who is responsible for sales of driverless transport systems. Already installed in 2021: bearing assemblies from Franke.

Franke bearing assemblies of the type LVA 350
Advantages utilized: Variety of variants, compactness, durability
“The size of the installed components plays a decisive role in the development of the overall system.”

Accuracy Unmatched…
Nils Kramm, responsible for the mechanical design of the transport systems, was already familiar with Franke technology from a previous job and from a research project with the Fraunhofer Institute. He and his colleagues opted for a practical ready-to-use solution from Franke to steer the driverless transport systems: bearing assemblies from the LVA series. In terms of size, Franke had exactly the right product in its program: “The size of the installed components plays a decisive role in the development of the overall system,” explains Kramm.
Franke bearing assemblies for the agile product variant with lifting unit…
Using the experience gained with its first driverless transport system, FFT has since developed the product further, and will continue to optimize it in the future. Franke bearing assemblies type LVA 350 are currently installed in the highest expansion stage of the transport system called FFTigv AGILITY. This comprises two drive units, each with a Franke bearing assembly for steering. The two wheels of a drive unit are driven and controlled individually. The FFTigv AGILITY is very agile when travelling with this drive: it can turn on the spot, drive crossways and turn at almost right angles. The equipment also includes a lift unit with a 150 mm stroke.
